To all whom it may concern.-

Be it known that I, MAX Gusrnv VoIc'r, Sn, a resident of New York city,in the county and State of New York, have invented an InnprovedWVire-Nail Machine, of which the following is a full, clear, and exactdescription,

reference being made tothe accompanying drawings, in which- Figures 1and 2 are top views of my improved wire-nail machine, showing the partsin different positions. Fig. 8 is a vertical longitudinal centralsection of the same. Fig. 4 is a detail side view showing part of themechanism for clamping the wire during the act of heading. Fig. 5 isavertical longitudinal central section of the wire clamping and headingmechanism, the parts being shown on an enlarged scale. Fig. 6 is anenlarged face view of one of the cutting-dies. Fig. 7 is an en largedtop view of the same. Fig. 8 is an enlarged end view of the same. Fig. 9is a horizontal section on the line 0 76, Fig. 5.

This invention relates to a new machine for making nails from continuouslengths of wire.

The invention consists of the novel combinations of parts, hereinaftermore fully described.

A in the drawings is the frame of the machine. Near one end this framecarries the transverse horizontal shaft B, to which continuous rotarymotion is imparted by suitable mechanism. This one shaft moves all theparts of the machine by means of the eccentric a, cams b b, eccentric d,crank e, and crank f, as follows, to wit: The eccentric a is embraced bya strap, 9, which carries a rod, h, that is pivoted at z to thehorizontally-longitudinally sliding carriage O. This carriage is guidedby rails j j, that are supported by the frame A. The part of thecarriage O which is farthest away from the shaft B has secured to it bya screw, Z, the header D. The back end of this header butts against ablock, in, that projects from the carriage 0. Thus the header isreciprocated.

The cams b I) serve to swing two lovers, E E, on vertical pivots n a.The ends of the levers E E which are farthest away from the shaft Benter slots in transverse horizontal slides F F. (See Figs. 6 and 7.)These slides carry at their inner ends the cutters G G. Springs 0 0connect with the levers E E, and tend to crowd them against the cams b.The ends of the levers E that bear against these cams are preferablyprovided with friction-rollers 1). Each slide F is slotted to receivethe end of a lever, E. The position of said lever in said slot can beregulated by a set-screw, q, Fig. 6, and by a sliding counter-piece, 0,which in turn is held in place by a screw, .9, all as shown in Figs. 6and 7. The screws q and s are sup ported by the slide F, as shown. Thecounterpiece r is slotted and guided on a pin, t.

Each cutter G is by its shank inserted between two lips, a u, thatproject from the slide F, and the said shank butts against a projection,2;, on the said slide. A screw, 10, holds the cutter in place. Thisscrew turns in a nut, x, which is inserted between the lips u a, fittinggrooves therein, as shown in Fig. 8; Should the screw w break, which mayoccur, the sliding nut x is moved out from between the lips, and a newscrew easily inserted. Whenever the cams b b crowd their ends of thelevers E E apart, the cutters G are brought together. When the cams nolonger crowd the lovers, the springs 0 0 will move the levers E E'so asto separate the cutters.

The slides F F are dovetailed in a block, H, which, by a screw orscrews, 3 (shown dotted in Fig. 5,) is secured to a rigidly-projectingledge, I, of the frame A. By means of the screw 3 and by set-screws zthe block H may be set somewhat nearer to or farther away from the shaft13, to thereby regulate the force of the cutters, which force should beincreased for thicker and decreased for thinner wire.

The eccentric d on the shaft B serves to depress one end of a lever, J,that is pivoted at a to the frame A. (See Fig. 4.) A spring, b holds thelever J in contact with the eccentric d. The pivot-pin a of the lever Jturns with the lever in its bearings and carries a crank-plate, 0*, (seeFig. 5,) that supports the lower wire-biting jaw, L. This jaw is placedbetween the block-H and the ledge I, and carries at its lower part anadjusting-screw, d", by means of which its. position vertically can beregulated. Above the lower jaw, L, is the upper jaw, M, which, by ascrew or screws, 6', is fastened to the ledge I. Thescrew 6 passesthrough a slot in the upper jaw, M, so as to allow the latter to beset.higher or lower by means of a small set-screw, f After the jaw M hasbeen adjusted to the proper height by the screw f it is tightly clampedin the desired position by the screw 6 \Vhcnever the eccentric ddepresses its end of the lever J, the cranloplate c lifts the jaw L, soas to crowd the wire against the I .1 jaw "\I.

The crank 6 slides in a grooved crank-plate, 9 which is mounted upon theshaft B, and connects by a rod, N, with a crank-shaft, O,

that is hung in the frame A behind theledge I, and that carries aserrated feed-wheel, h". This feed-wheel meshes into a sliding rack, i,which carries a spring-pawl, j This spring-pawl, together with saidrack, is intended to feed the wire P forward through a hole in the ledgeI, and between the jaws L M and cutters G G. Vhenever the wheel h isturned to move the rack 1'," toward the ledge I, the pawl j will bitethe wire and feed it along; but whenever the wheel h isturned in theopposite direction the pawl will slide loosely on the wire withoutaffecting its position. The wire P, before reaching the pawl j", may beguided between grooved friction rollers k The cam f on the shaft Bprojects longitudinally, as shown in Fig. 2, and serves to depress oneend. of a lever, R, that is pivoted at Z in projecting posts of theframe A, said lever B at its free end that is, the end which is farthestaway from the shaft Bconnectingwith a vertically-sliding ejector, S,which is guided in posts m that project from the frame A. A spring, it",serves to depress the ejector and to lower the end of the lever Bwhenever the cam f shall have passed it. When the ejector is lowered bythe action of the spring, its point enters between the receding header Dand the cutters G G. The cam f serves to lower one end of the lever B,and

thereby to lift the ejector. -I have now described the construction ofthe machine.

The operation will be understood from what has been said, but in orderto avoid any misunderstanding it will here be briefly recapitulated.

The wire P is fed forward by the feeding mechanism 2' j until itprojects a certain proper distance beyond the face of the jaws L M. Thecutters G G at this time are drawn The jaws L M now take hold of andapart.

bite the wire between them. Next the header D is projected against thewire that extends bevond the face of the jaws L M and forms (See Fig.3.) Theheader the head thereon.

now recedes, the jaw L is lowered, the wire P is fed further forward,and then the cutters G G approach one another and cut off the headedpiece of wire which was between them. Immediately after this the ejectorS descends to expel or throw down the wire nail thus separated,whereuponthe operation continues, as already stated.

The cutting ends of the cutters G G are represented more plainly inFigs. 5 and 8, from which figures it will appear that each of thesecutters has a V-knife, 0 facing the header, and behind this V-knife avertical knife, 10. The V-knives of the two cutters form the point ofthe finished nail, while the vertical knife 12 cuts the blunt end fromwhich the head of the next nail is to be made.

I call attention to the very simple construction of my machine, to thefact that all the motions thereof are derived from a single shaft, B,and that all the actuating parts are readily adjusted. Thus the play ofthe cutters can be regulated as has been described, the force of theirthrow can. be adjusted, the motion of the jaw L is adjustable, and theparts most exposed to destructionthat is, the headers and cutters-areremovable and readily replaced.
